FPGA solution to VME component obsolescence

1 min read

Despite it being 35 years since the standard was introduced, VME systems remain in widespread use. The problem, however, is that many of the components that underpinned VME in its earlier days have now become obsolete or are at the end of the production lives.

One popular solution has been IDT’s TSI148 VMEbus bridge, which links VME systems to PCI Express processors and peripherals. However, this has now entered end of life. In response, Abaco Systems has developed Vivo, an FPGA based solution that replicates its functionality.

“Many of our customers have made a substantial investment in VME based systems – and often those are highly complex systems that are deployed in mission critical environments,” said Chris Lever, Abaco’s VP of product management. “For those customers, transitioning to an alternative architecture was unthinkable. It was vital for them to see a way forward – and Vivo provides them with the reassurance they will be able to create, maintain and update VME based systems well into the future.”

According to Abaco, Vivo supports 2eSST for full VITA 1.5 capability, as well as hardware byte swapping and a master/slave interface with A16, A24 and A32 addressing modes.

The company adds that long term availability of Vivo is ‘assured’, and says it will be incorporated into future generations of its VMEbus single board computers based on Intel and Power Architecture technology.
